What is a checksum and how is it used with a database backup?

What will be an ideal response?


A checksum is a unique variable that is computed based on the data contained in a page and used to verify the integrity of the data. When a restore operation later reads the page from storage, it also computes a checksum and checks that this matches the stored value. A match indicates that the integrity of the data has likely been retained.

(Recursive Exponentiation) Write a recursive function power( base, exponent ) that, when invoked, returns base exponent For example, power( 3, 4 ) = 3 * 3 * 3 * 3. Assume that exponent is an integer greater than or equal to 1. Hint: The recursion step would use the relationship base exponent = base ยท base exponent - 1 and the terminating condition occurs when exponent is equal to 1, because base1 = base
